Title:
OPTIMIZED EXPECTATION PROPAGATION DETECTION METHOD AND SIGNAL DETECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/031979
Kind Code:
A1
Abstract:
The present application relates to an optimized expectation propagation detection method and a signal detection apparatus. The method comprises: first, acquiring code information of a uncoded bit sequence, modulation information, a channel matrix between a sending end and a receiving end, and a receiving signal, and constructing a linear programming model; determining the prior probability of a sending symbol and initial parameters according to the linear programming model; performing first iterative convergence operations according to the prior probability of the sending symbol and the initial parameters so as to obtain a target log-likelihood ratio of a corresponding uncoded bit sequence at the end of a preset first iterative convergence operation; and, according to the target log-likelihood ratio, determining a uncoded bit sequence.
